I used the Scorp-o-matic [very useful, a great idea] and it recommends either Hadrurus Arizonensis or Pandinus cavimanus.

Now, im wavering because I deliberately chose a desert species first time round so that I would not need to deal with balancing humidity. However, im feeling much more confident now and building a false bottom and doing some misting seems simple enough.

Thing is, I'd never seen pictures of Pandinus cavimanus and it is a gorgeous looking scorpion. I'm very tempted to tear apart my vivarium and rebuild it in a forest set-up. Bonus is, the company I ordered my last scorpion from have Cavimanus in stock.
